In the present embodiment, the fuel consumption acquisition unit 43 starts the fuel consumption integration when the condition (2-1) is satisfied at the time when the traveling speed of the vehicle 200 becomes zero and the integration condition is satisfied. .. During the period from the time when the vehicle 200 is stopped until 5 minutes, which is a predetermined period, elapses, the fuel consumption acquisition unit 43 acquires the integrated value of the fuel consumption as the short-term stop fuel consumption. The fuel consumption acquisition unit 43 integrates the fuel consumption during the period from time T2 to time T3, that is, the short-term stop fuel consumption.

時間T4から時間T5までの期間、車両200は、予め定められた期間以上において停車している。本実施形態において、車両200の停車状態が車両200の停車時点から予め定められた期間である5分以上継続する場合、燃料消費量取得部43は、車両200の停車時点から5分を経過するまでの期間、短期停止燃料消費量としての燃料消費量の積算値を取得し、停車時点から5分を経過した以降の期間において、条件(2−1)が成立せず、積算条件を満たしていないと判定して、燃料消費量の積算を停止する。図4では、時間T4から時間T4sまでの期間は予め定められた期間と等しいため、燃料消費量取得部43は、車両200の停車時点である時間T4から時間T4sまでの期間、短期停止燃料消費量としての燃料消費量を積算し、積算値C1sを取得する。停車時点から5分を経過した時間T4sから走行を再開する時間T5までの期間、燃料消費量取得部43は、燃料消費量の積算を停止する。
なお、図4の推移Caとして示すように、時間T4から時間T5までの期間において、車両200は、いわゆるアイドリングとも呼ばれる走行可能状態での停車であり、燃料電池30による燃料を消費し、燃料消費量は増加する。
During the period from time T4 to time T5, the vehicle 200 is stopped for a predetermined period or longer. In the present embodiment, when the stopped state of the vehicle 200 continues for 5 minutes or more, which is a predetermined period from the stopped time of the vehicle 200, the fuel consumption acquisition unit 43 elapses 5 minutes from the stopped time of the vehicle 200. In the period until, the integrated value of the fuel consumption as the short-term stop fuel consumption is acquired, and in the period after 5 minutes have passed from the time of stopping, the condition (2-1) is not satisfied and the integrated condition is satisfied. It is determined that there is no fuel consumption, and the accumulation of fuel consumption is stopped. In FIG. 4, since the period from the time T4 to the time T4s is equal to the predetermined period, the fuel consumption acquisition unit 43 consumes the short-term stop fuel during the period from the time T4 to the time T4s when the vehicle 200 is stopped. The fuel consumption as the amount is integrated, and the integrated value C1s is acquired. During the period from the time T4s, which is 5 minutes after the vehicle is stopped, to the time T5, which is the time when the vehicle is restarted, the fuel consumption acquisition unit 43 stops the accumulation of the fuel consumption.
As shown by the transition Ca in FIG. 4, in the period from time T4 to time T5, the vehicle 200 is stopped in a runnable state, which is also called idling, and consumes fuel from the fuel cell 30 and consumes fuel. The amount increases.

時間T6から時間T7までの期間、燃料電池30の掃気処理が実行されている。本実施形態において、燃料電池30の掃気処理を実行する期間は積算条件を満たすため、燃料消費量取得部43は、時間T6から時間T7までの期間の燃料消費量、すなわちFC処理燃料消費量の積算を行う。時間T7において、推移CSの燃料消費量の積算値はC2であり、推移Caの燃料消費量の積算値はC3である。積算値C2は、時間T4sから時間T5までの燃料消費量が積算されない分だけ、積算値C3よりも小さい。時間T7において、車両200への燃料の補充が実行されると、燃費算出部47は、時間T0から時間T7までの燃料補充期間の走行距離の積算値と、燃料消費量の積算値C2とを用いて燃料補充間燃費を算出する。積算値C2を用いて算出された燃料補充間燃費は、時間T4sから時間T5までの車両200の停車期間中の燃料消費量が積算されない分、積算値C3を用いて算出された燃料補充間燃費よりも大きくなる。積算値C2を用いて算出された学習燃費および航続可能距離も同様に、積算値C3を用いる場合よりも大きくなる。 The scavenging process of the fuel cell 30 is executed during the period from time T6 to time T7. In the present embodiment, since the period during which the scavenging process of the fuel cell 30 is executed satisfies the integration condition, the fuel consumption acquisition unit 43 determines the fuel consumption during the period from time T6 to time T7, that is, the FC processed fuel consumption. Accumulate. At time T7, the integrated value of the fuel consumption of the transition CS is C2, and the integrated value of the fuel consumption of the transition Ca is C3. The integrated value C2 is smaller than the integrated value C3 because the fuel consumption from the time T4s to the time T5 is not integrated. When the vehicle 200 is refueled at the time T7, the fuel consumption calculation unit 47 calculates the integrated value of the mileage during the refueling period from the time T0 to the time T7 and the integrated value C2 of the fuel consumption. It is used to calculate the fuel consumption during refueling. The fuel consumption between refueling calculated using the integrated value C2 is the fuel consumption between refueling calculated using the integrated value C3 because the fuel consumption during the stop period of the vehicle 200 from the time T4s to the time T5 is not integrated. Will be larger than. Similarly, the learning fuel consumption and the cruising range calculated using the integrated value C2 are also larger than those when the integrated value C3 is used.

以上、説明したように、本実施形態の航続可能距離提示装置100によれば、車両200が走行の準備中および走行中である場合の走行期間燃料消費量を用いて燃料補充期間燃費Crが算出される。車両200の停止時の燃料消費量を含まず走行時に使用される燃料消費量を用いて燃料補充期間燃費が算出される。そのため、車両200の走行に必要な燃料消費量に基づく適正な航続可能距離を算出して提示することができる。 As described above, according to the cruising range presenting device 100 of the present embodiment, the fuel consumption Cr during the refueling period is calculated using the fuel consumption during the traveling period when the vehicle 200 is preparing for traveling and during traveling. Will be done. The fuel consumption during the refueling period is calculated using the fuel consumption used during traveling, not including the fuel consumption when the vehicle 200 is stopped. Therefore, an appropriate cruising range based on the fuel consumption required for the vehicle 200 to travel can be calculated and presented.

本実施形態の航続可能距離提示装置100によれば、学習燃費算出部48は、前回の学習燃費Cg(n−1)と、燃料補充期間での燃料補充期間燃費Crとの加重平均によって今回の学習燃費Cg(n)を算出する。学習燃費が補充タイミングごとに順次に更新されるので、車両200の走行実績に基づいて燃費の算出精度を高めることができる。加重平均を用いることにより、燃料補充期間ごとの燃料消費量のばらつきの影響を抑制することができる。 According to the cruising range presenting device 100 of the present embodiment, the learning fuel consumption calculation unit 48 is based on the weighted average of the previous learning fuel consumption Cg (n-1) and the fuel consumption period fuel consumption Cr in the refueling period. The learning fuel consumption Cg (n) is calculated. Since the learned fuel consumption is sequentially updated at each replenishment timing, the calculation accuracy of the fuel consumption can be improved based on the running record of the vehicle 200. By using the weighted average, the influence of the variation in fuel consumption for each refueling period can be suppressed.

本実施形態の航続可能距離提示装置100によれば、燃費算出部47は、燃料補充期間燃費Crの算出において、走行期間燃料消費量に、さらに、車両200が予め定められた期間未満において停車した際の短期停止燃料消費量、を含める。車両200の走行中に発生する一時的な停車による燃料消費量を燃料補充期間燃費に反映させることにより、車両200の走行の実情に近い条件下での航続可能距離を算出して提示することができる。 According to the cruising range presenting device 100 of the present embodiment, the fuel consumption calculation unit 47 stops the vehicle 200 in less than a predetermined period in the calculation of the fuel consumption Cr during the refueling period in addition to the fuel consumption during the traveling period. Includes short-term outage fuel consumption, when. By reflecting the fuel consumption due to the temporary stop generated while the vehicle 200 is running in the fuel consumption during the refueling period, it is possible to calculate and present the cruising range under conditions close to the actual driving situation of the vehicle 200. can.

本実施形態の航続可能距離提示装置100によれば、燃費算出部47は、燃料補充期間燃費Crの算出において、走行期間燃料消費量に、さらに、燃料電池30の掃気処理および暖機処理を実行する期間の燃料消費量であるFC処理燃料消費量、を含める。燃料電池車両の走行に必要な燃料電池30の処理による燃料消費量を燃料補充期間燃費の算出に反映することにより、燃料電池車両の走行の実情に近い条件下での航続可能距離を算出して提示することができる。 According to the cruising range presenting device 100 of the present embodiment, the fuel consumption calculation unit 47 executes the scavenging process and the warm-up process of the fuel cell 30 in addition to the running period fuel consumption in the calculation of the fuel replenishment period fuel consumption Cr. Includes FC-processed fuel consumption, which is the fuel consumption during the period. By reflecting the fuel consumption due to the processing of the fuel cell 30 required for the running of the fuel cell vehicle in the calculation of the fuel consumption during the refueling period, the cruising range under conditions close to the actual running of the fuel cell vehicle is calculated. Can be presented.

B.他の実施形態:
(B1)図5は、他の実施形態での燃料消費量取得部43による燃料消費量の積算値の推移を模式的に表す説明図である。図5には、参考例として、第1実施形態での燃料消費量の積算値の推移CSと、燃料電池30で実際に消費される燃料消費量の積算値の推移Caとが破線で示されている。上記第1実施形態において、車両200の停車状態が停車時点から予め定められた期間以上継続する場合には、燃料消費量取得部43は、車両200の停車時点から予め定められた期間を経過するまでの期間、短期停止燃料消費量としての燃料消費量の積算し、停車時点から予め定められた期間を経過した以降の期間において、燃料消費量の積算を停止する。これに対して、燃料消費量取得部43は、車両200の停車状態が停車時点から予め定められた期間を経過した場合に、車両200の停車時点から燃料消費量を積算するか否かにかかわらず、車両200の停車時点の燃料消費量の積算値を、車両200の停車期間が終了した時点での燃料消費量の積算値として用いてよい。例えば、図5の推移CS2として示すように、車両200の停車時点である時間T4から燃料消費量の積算を開始し、予め定められた期間を経過した時間T4sにおいて、時間T4から時間T4sまでに積算した燃料消費量の積算値C1sを破棄して、車両200の停車時点での燃料消費量の積算値C1を積算値としてメモリに記憶させる。車両200の走行を再開する時間T5では、積算値C1に対して燃料消費量の積算を継続してよい。車両200の停車期間に積算した燃料消費量の積算値を破棄して、車両200の停車時点での燃料消費量の積算値C1を積算値としてメモリに記憶させるタイミングは、例えば、時間T5において車両200の走行を再開した時点であるなど、時間T4から時間T5までの任意の時点であってもよい。この形態の航続可能距離提示装置100によれば、長期停車時の燃料消費量をより正確に算出することで、走行時に使用される燃料消費量をより正確に算出することができる。したがって、より適正な航続可能距離を算出して提示することができる。
B. Other embodiments:
(B1) FIG. 5 is an explanatory diagram schematically showing a transition of an integrated value of fuel consumption by the fuel consumption acquisition unit 43 in another embodiment. In FIG. 5, as a reference example, the transition CS of the integrated value of the fuel consumption in the first embodiment and the transition Ca of the integrated value of the fuel consumption actually consumed by the fuel cell 30 are shown by broken lines. ing. In the first embodiment, when the stopped state of the vehicle 200 continues for a predetermined period or longer from the time when the vehicle is stopped, the fuel consumption acquisition unit 43 elapses a predetermined period from the time when the vehicle 200 is stopped. During the period until, the fuel consumption as the short-term stop fuel consumption is accumulated, and the fuel consumption is stopped in the period after the predetermined period has passed from the time of stopping. On the other hand, the fuel consumption acquisition unit 43 determines whether or not the fuel consumption is integrated from the time when the vehicle 200 is stopped when the stopped state of the vehicle 200 has passed a predetermined period from the time when the vehicle 200 is stopped. Instead, the integrated value of the fuel consumption at the time when the vehicle 200 is stopped may be used as the integrated value of the fuel consumption at the end of the stop period of the vehicle 200. For example, as shown as the transition CS2 in FIG. 5, the fuel consumption integration is started from the time T4 at the time when the vehicle 200 is stopped, and at the time T4s after the predetermined period has elapsed, from the time T4 to the time T4s. The integrated value C1s of the accumulated fuel consumption is discarded, and the integrated value C1 of the fuel consumption at the time when the vehicle 200 is stopped is stored in the memory as the integrated value. At the time T5 for resuming the running of the vehicle 200, the fuel consumption may be continuously integrated with respect to the integrated value C1. The timing at which the integrated value of the fuel consumption accumulated during the stop period of the vehicle 200 is discarded and the integrated value C1 of the fuel consumption at the time when the vehicle 200 is stopped is stored in the memory as the integrated value is, for example, at time T5. It may be at any time from time T4 to time T5, such as when the running of 200 is resumed. According to the cruising range presenting device 100 of this form, the fuel consumption during long-term stop can be calculated more accurately, so that the fuel consumption used during traveling can be calculated more accurately. Therefore, a more appropriate cruising range can be calculated and presented.

On the other hand, the learning fuel consumption calculation unit 48 may calculate the learning fuel consumption Cg (n) by using, for example, the weighted average of the fuel consumption period fuel consumption Cr calculated this time and the fuel consumption period fuel consumption Cr calculated last time. good. According to the cruising range presenting device 100 of this form, the learning fuel consumption using the most recently calculated refueling period fuel consumption Cr can be calculated.

(B3)上記実施形態では、制御装置40は、学習燃費算出部48を備える。これに対して、制御装置40は、学習燃費算出部48を備えなくてもよい。この形態の航続可能距離提示装置100において、航続可能距離算出部49は、燃費算出部47により算出された燃料補充期間燃費Crと、燃料の残量とを用いて前記燃料電池車両の航続可能距離を算出する。この形態の航続可能距離提示装置100であっても、車両200の停止時の燃料消費量を含まず走行時に使用される燃料消費量を用いて燃料補充期間燃費が算出されるので、車両200の走行に必要な燃料消費量に基づく適正な航続可能距離を算出して提示することができる。 (B3) In the above embodiment, the control device 40 includes a learning fuel consumption calculation unit 48. On the other hand, the control device 40 does not have to include the learning fuel consumption calculation unit 48. In the cruising range presenting device 100 of this form, the cruising range calculation unit 49 uses the refueling period fuel consumption Cr calculated by the fuel consumption calculation unit 47 and the remaining amount of fuel to cruising the cruising distance of the fuel cell vehicle. Is calculated. Even in this form of the cruising range presenting device 100, the fuel consumption during the refueling period is calculated using the fuel consumption used during traveling without including the fuel consumption when the vehicle 200 is stopped. Therefore, the fuel consumption of the vehicle 200 is calculated. It is possible to calculate and present an appropriate cruising range based on the fuel consumption required for driving.

It has been described as an example that at least one of the three conditions is satisfied. On the other hand, when the integration condition is satisfied, it is set as the case where the acquisition result of the operation of the vehicle 200 is not the external power supply mode, the emergency power supply mode, or the abnormal state, and only the condition (1) is satisfied. May be done. The running period fuel consumption does not have to include the short-term stop fuel consumption and the FC processed fuel consumption. Even in this form of the cruising range presenting device 100, the fuel consumption during the replenishment period can be reduced by using the fuel consumption consumed by the running of the vehicle 200 without using the fuel consumption when the vehicle 200 is stopped.

It has been described as an example that at least one of the three conditions is satisfied. On the other hand, when the integration condition is satisfied, the acquisition result of the operation of the vehicle 200 is not in the external power supply mode, the emergency power supply mode, or the abnormal state, and at least one of the condition (1) and the condition (2). It may be set as the case where the above condition is satisfied. The running period fuel consumption may include short-term stop fuel consumption and may not include FC processed fuel consumption. Even in this form of the cruising range presenting device 100, the fuel consumption during the replenishment period can be reduced by using the fuel consumption consumed by the running of the vehicle 200 without using the fuel consumption when the vehicle 200 is stopped.
